1.0 - Introduction
This technical memorandum summarizes the traffic analyses conducted by Minagar & Associates,
Inc. in support of the California Environmental Quality Act (CEQA) for the North Atwater
Non-Motorized Bridge Project over the Los Angeles River in the Atwater Village area of Los
Angeles, California. The CEQA process requires identification and analysis of the significant
environmental effects of the proposed project. In assessing the impact of a proposed project on
the environment, the examination focuses on changes in the existing physical conditions of the
existing affected area. The following report describes these existing traffic and transportation
conditions within the project study area, the potential impacts of the project, the
methodologies used to evaluate the potential impacts, and finally, the impact of the project
upon build-out conditions.
Figure 1 illustrates the project location and study area.
The North Atwater Bridge Project consists of a pre-fabricated 36-foot wide cable stayed bridge
which will span approximately 390 feet across the Los Angeles River. The bridge crossing will
provide pedestrian and equestrian access from the east side of the river to Griffith Park on the
west side of the River and I-5 Freeway. Additionally, the bridge will provide bicycle access from
Atwater Park (located just north of the proposed bridge and on the east side of the river) to
the L.A. bicycle trail system along the west bank of the L.A. River.
As proposed, the North Atwater Multimodal Bridge will carry only pedestrian, bicycle and
equestrian traffic. Due to this conditional non-motorized element, and per the concurrence of
Los Angeles Department of Transportation (LADOT) staff, the North Atwater Bridge project is
pre-determined to not generate any additional vehicle trips, and thus is categorically exempt
from standard traffic impact analysis requirements.

Nonetheless, the project team does acknowledge the potential for the project to temporarily
disrupt traffic flow on the adjacent I-5 Northbound freeway lanes, due to need to close one or
two lanes during various hours during the construction phase.
This report identifies three key traffic study components:
■ (1) Temporary (Construction Period) Traffic Impacts—Since the project will not
generate any project trips, only freeway mainline Level of Service (LOS) changes
resulting from lane closures are presented;
■ (2) Temporary (Construction Period) Impacts to Multi-modal (i.e., Pedestrian,
Bicycle and Equestrian) Traffic—Including temporary travel path closures and
detours; and
■ (3) Identification of project features to mitigate potential any temporary and/or
permanent traffic and transportation impacts
For the first traffic study component, Highway Capacity Manual (HCM) Freeway Mainline
Analysis methods were used to evaluate the impact of the project construction activities during
various hours of the day on the adjacent Northbound I-5 Freeway segment between Los Feliz
Boulevard and Colorado Boulevard. The project as proposed will require the use of the
adjacent freeway shoulder and one (1) through lane on the adjacent I-5 freeway mainline
segment. For a conservative analysis, a maximum of two (2) through lanes was used for
evaluating project construction impacts. Given the project duration of less than 12 months, the
analysis was limited to the following two traffic scenarios:
■ I. Existing (2012) conditions
■ II. Existing (2012) Plus Project conditions
The results of the analyses reveal that the construction of the proposed Atwater
Multimodal/Non-Motorized Bridge Crossing Project will result in insignificant traffic impacts
upon the adjacent Northbound I-5 Freeway mainline segment during the construction period.

Based on the traffic impact analysis of the adjacent northbound I-5 freeway lanes, an acceptable
Level of Service (i.e., LOS “C” or better) can be maintained if project-related lane closures on
the mainline are conducted within the following time periods:
■ Monday through Thursday:
o Morning- 12AM to 6AM
o Evening- 8PM to 12AM
■ Friday:
o Morning- 12AM to 6AM
o Evening- 8PM to 9AM
■ Saturday:
o Morning- 12AM to 9AM
o Evening- 10PM to 12AM
■ Sunday:
o Morning- 12AM to 10AM
o Evening- 9PM to 12AM
However, as a conservative measure, and based on discussions with Caltrans staff, the
proposed highway lane closures for this project would occur only on typical weekend days
(Saturday/Sunday), and during the overnight period between 10PM and 6AM. It is expected
that during these hours, traffic conditions hours would return to baseline levels upon
conclusion of the construction phase, and therefore any traffic impacts due to the lane
closures would be de minimis and temporary.

2.0 - Existing Conditions
The proposed Atwater Multimodal
Crossing is a response to a series of
conditions on several scales. From a
traffic/transportation perspective, the
bridge crossing will serve to provide
connectivity and access on a
multimodal basis from the
neighborhoods to the east to Griffith
Park on the west. The crossing will
allow safe access for equestrian users
from the stable complexes on the east
to Griffith Park. Additionally, the bridge will allow for bicycle access from Atwater Park to the
Los Angeles River segment of the L.A. bicycle trail system. The existing site is physically
constrained in terms of available space for construction staging, delivery of bridge components,
materials and equipment storage, and actual on-site construction and bridge assembly. As
shown in the image below, the Northbound I-5 Freeway abuts the existing L.A. River bicycle
path along the west side of the riverbank. The adjacent freeway shoulder and lanes will require
periodic closures for delivery of bridge components constructed off-site and then assembled at
the project site. Lane closures will only be required during delivery of the components.

2.1 - Existing Pedestrian, Bicycle and Equestrian Facilities
The existing non-motorized transportation facilities are composed of the following elements:
■ Los Angeles Greenway Trail—Pedestrian path on the east side of the L.A. River. Nearest local
street access points are located at Colorado Boulevard to the north, and Los Feliz Boulevard to
the south.
■ Los Angeles River Bike Way—Class II paved bicycle path on the west side of the L.A. River.
Nearest access points are located around the river “bend” at Victory Boulevard/Riverside Drive
(to the north), and at the dedicated overcrossing across Los Feliz Boulevard (to the south). An
existing access tunnel (Tunnel #1) is located under the I-5 Freeway alignment which connects
the bikeway to the proceeding Griffith Park trails to the west of the freeway.
■ Equestrian Horse Trail and River Crossing—Part of the L.A. Greenway Trail, includes a
equestrian bridle path which runs adjacent to the pedestrian walkway from Los Feliz Boulevard
to North Atwater Park. Two traversable slopes run alongside each embankment from the
riverbed to the top of the proposed bridge alignment, serving as a crossing point for equestrian
traffic between the west and east sides of the river.
■ Glendale Narrows Riverwalk—Non-motorized improvement projects along the L.A. River,
located north of the proposed North Atwater Bridge along the River “bend” near the I-5/SR-
134 confluence. As of April 2012, the Phase I of the City of Glendale's Glendale Narrows
Riverwalk is still under construction along the north bank of the L.A. River, opposite of Griffith
Park. The project includes half a mile of recreational trail for bicyclists and pedestrians, two
small parks, an equestrian facility, landscaping, and additional trail features, and is expected to be
completed during this Fall. A large portion of the second phase of the project has already been
constructed, which will ultimately include an extension of the bicycle/pedestrian path eastward
and south around the river bend to the Verdugo Wash. A final future phase will include the Los
Angeles River Bridge connecting the Riverwalk to Griffith Park across the L.A. River, and the
Verdugo Wash Bridge, which will connect the Riverwalk to North Atwater across the Verdugo
Wash confluence with the Los Angeles River.

2.2 - Existing Traffic Volumes
Existing 24-hour traffic counts were obtained from Caltrans District 7 for the Northbound
Interstate 5 (I-5) Freeway Segment between Los Feliz Boulevard and Colorado Boulevard. The
hourly data was provided by Caltrans as collected from its Performance Measurement System
(PeMS) freeway monitoring database and mainline loop sensors for the month of April 2012.
Table 1 shows the full traffic volume data set used in the analysis, which includes both
passenger cars and heavy vehicles. Heavy vehicle splits for 3-axle, 4-axle and 5-axle trucks were
obtained from Caltrans Traffic Volume Branch's most recent database, and applied to the
Highway Capacity Manual (HCM) analysis.
2.3 - Existing Level of Service Analysis
Using the data mentioned above, a Level of Service (LOS) analysis was conducted for the
Northbound I-5 Freeway mainline segment located to the west and adjacent to the project site.
The analyses were conducted using the appropriate procedures from the Highway Capacity
Manual (HCM)(Transportation Research Board) as per Caltrans' latest Traffic Impact Analysis
Guidelines. Additional analysis inputs for the existing freeway mainline segment are as follows:
■ Number of Lanes: 5
■ Average Lane Width: 12'
■ Right Shoulder Lateral Clearance: 12'
■ Interchange Density: 0.75 per mile (8 per 6 miles)
■ Peak Hour Factor, PHF: 0.95 (typical urban freeway)
■ Driver Population Factor: 1.00 Monday through Friday, 0.95 Saturday/Sunday due to
Griffith Park and L.A. Zoo trip attractors
■ Passenger Car Equivalents, PCE: 2-Axle=1.5, 3-Axle=2.0, 4-Axle=3.0

2.4 - Existing Freeway Mainline Levels of Service (LOS)
In accordance with the policies established by Caltrans, the "Operational Analysis" method
from HCM for freeway mainline segments was used to perform the Level of Service (LOS)
analysis. The HCM operational method determines two key operating characteristics of
freeway mainline segments: (1) the average passenger car speed, and (2) the traffic density in
terms of passenger cars per mile per lane (pcpmpl). These two outputs are then converted into
an LOS value for the basic freeway segment, ranging from excellent, nearly free-flow conditions
at LOS A to heavily-congested, slow speed conditions at LOS F. The LOS definitions and the
relationship between LOS and mainline segment traffic density are shown in Table 2.
TABLE 2
Caltrans Level of Service (LOS) Criteria
Caltrans' desired LOS range for freeway mainline segments is at the transition between LOS
“C” and LOS “D” for State highway facilities. If a segment is forecasted to fall to LOS D under
the project conditions, mitigation measures should be pursued. If the State highway facility is
currently operating at less than the appropriate target LOS, the existing level of service should
be maintained.

Table 3 presents the results of the existing freeway mainline level of service calculations during
various peak times of the day and week. As shown in Table 3, the Northbound I-5 Freeway
segment between Los Feliz Boulevard and Colorado Boulevard is operating LOS C or better
during all hours of the day and days of the week.
3.0 - Forecast Conditions
3.1 - Existing Plus Project Level of Service
Traffic forecasts were prepared for the NB I-5 mainline segment between Los Feliz Boulevard
and Colorado Boulevard. The methodology for developing the "project condition" included a
reduction in the number of available through lanes due to construction lane closures, and
elimination of factors for right shoulder lateral clearance.
Based on the project team's estimation, the construction phase will require closure of the
adjacent freeway shoulder, as well as one (1) through lane on the adjacent I-5 freeway mainline
segment to allow for the delivery and loading/unloading of materials and equipment. To provide
a conservative analysis, however, a total of two (2) through lanes were assumed for the lane
closure and in evaluating potential project construction impacts, as shown in Figure 2, below.
Caltrans District 7 (D7) provided Lane Requirements and Hours of Work charts for the
subject freeway segment. Combined with the above assumptions, Caltrans' lane/hours charts
were used to develop a "worst case" scenario for the various peak hours of the day, and days
of the week. The resulting LOS calculations comparing Existing Year 2012 conditions, Existing
Year 2012 conditions with the maximum permitted lane closures, and the Existing Year 2012
conditions with project-related lane closures, are shown below on Table 3.

The LOS summary on Table 3 reveals that the existing Northbound I-5 Freeway segment north
of Los Feliz Boulevard, when operating at the upper limit of Caltrans' permitted work hours
and lane requirements, falls into the LOS D/E range during various hours each day. However,
under the proposed two-lane closure project conditions, the freeway mainline segment would
maintain an acceptable LOS "C" or better during all hours and days. The only exceptions occur
when freeway mainline segment operations fall to LOS "D" during the 8:00PM-11:00PM period
from Monday to Thursday, and during the 9:00PM-11:00PM period on Sunday. In these two
cases, the Traffic Management Plan (TMP) should limit project construction activities to closure
of only one (1) through lane and/or the only existing 12’ paved shoulder, in order to retain a
minimum mainline LOS of “C”.
The Freeway Mainline Analysis Level of Service worksheets are provided in Appendix A of
this technical memorandum.
4.0 - Construction Impacts
4.1 - Temporary Construction-Related Effects on Access and Circulation
Construction for this project is expected to start fall of 2012 and be completed in the fall of
2013. Under the proposed project condition, temporary construction activities would not
result in any disruption to access or circulation as there will be no restriction to vehicular on-
or off-ramp access between the highway and local street system. No permanent barriers to
local communities will occur, and existing vehicular access points and circulation routes to and
from the surrounding area would remain open.
Access to the nearby interchanges at Los Feliz Boulevard and Crystal Springs Dive (to the south)
and Colorado Boulevard (to the north) would not be affected by the construction activities

associated with the proposed project. Construction activity would be temporary, and limited to
localized, site-specific activities in the immediate vicinity of the proposed project along the
subject portion of the River. The anticipated temporary effects would be primarily related to
trucks and equipment on the roadside, and partial and/or complete lane closures on the
adjacent I-5 freeway segment. Increased traffic from construction equipment and heavy trucks
traveling to and from the project site in this area would be insignificant and, construction-
related effects would be minimal.
Given the above conditions, no permanent adverse effects to local or regional traffic access or
circulation are anticipated with implementation of the proposed project. Therefore, no
avoidance, minimization, and/or mitigation measures are proposed to compensate for any offset
or change in traffic access or circulation.
4.2 - Traffic Management Plan (TMP)
A Traffic Management Plan (TMP), a standard condition placed on all construction projects, is
designed to minimize construction activity-related motorist delays, queuing, and accidents by
the effective application of traditional traffic-handling practices and innovative approaches. The
TMP will include measures to offset traffic congestion and maintain traffic flow throughout the
alternative routing and surrounding area on the adjacent I-5 Freeway, and throughout the local
north Atwater and Los Feliz neighborhoods within the project area. The preliminary TMP will
include proposed Lane Closure Charts and Detour Plans as approved by Caltrans, and will be
finalized by the time final designs are prepared. However, it is certain that a minimum of three
(3) lanes would be kept open at all times in the northbound direction, and all five (5) lanes in
the southbound direction.
The final TMP will include traffic mitigation strategies for the duration of construction, address
lane closure requirements, and seek to inform the public and motorists. TMP strategies will
include: project phasing, a detour plan(s), and provision of temporary lanes/shoulders. Traffic

management strategies will also include a multi-modal public awareness effort, traffic systems
and signage, and traffic support and safety elements for re-routing existing bicycle, pedestrian
and equestrian traffic around the construction area. The public awareness element will generally
involve distribution of brochures, mailers, and/or media releases in cooperation with the City of
Los Angeles and the local community, in order to educate and inform the public of the
construction activities. Motorist information strategies would include message signage and a
highway advisory radio (HAR) to alert motorists of road closures and/or detours. Static signage
would be used for non-motorized path closures for the duration of the project.
4.3 - Pedestrian, Bicycle and Equestrian Traffic Impacts
The California Code of Regulations Streets and Highways Code Sections 890-894.2, the
California Bicycle Transportation Act, discusses the importance of a non-motorized
transportation system, establishes bikeway specifications and encourages local agency
participation in developing improved bikeways. California Code of Regulations Streets and
Highways Code Sections 894.6-894.8, the California Pedestrian Safety Act, encourages projects
that address pedestrian safety.
By design, the North Atwater Multimodal Bridge Project should have beneficial traffic and
transportation impacts and would not contribute to cumulative adverse effects. To improve the
safety and accessibility of non-motorized traffic across the L.A. River, the designed bridge
provides a cross section and deck width that sufficiently accommodates Class II bike traffic,
pedestrians and equestrians in both directions. The proposed paved bicycle and pedestrian
paths on each of the east and west riverbanks are equal to the widths of the existing paths
approaching the construction area to provide a continuous multimodal facility.
The proposed project may cause disruptions in the existing non-motorized traffic along the L.A.
River during the construction period, due to potential bikeway and pedestrian path closures
and restricted local access to the River near the construction area. The closure of entry gates

__________________________________________________________________________________ 18
08/06/2012
into the L.A. River Greenway Trial (east side) and L.A. River Bike Path (west side) during the
construction period would result in local street detours that may impact non-motorized users
in the community who regularly travel along the L.A. River paths.
The proposed project would temporarily close the pedestrian and bicycle access points into the
L.A. River at Los Feliz Boulevard (to the south), Colorado Boulevard (to the north), and at the
existing access tunnel to Griffith Park under the I-5 Freeway. The closure would block
pedestrian and equestrian access to North Atwater Park from the south, and restrict bicycle
travel along the L.A. River between Colorado Boulevard and Los Feliz Boulevard for
approximately 12 months during the construction of the bridge structure and rehabilitation of
associated non-motorized components. The pedestrian, bicycle and equestrians paths on each
side of the river would be reopened after construction is complete.
Temporary project impacts are defined as those that would occur during the construction of
the proposed project. These temporary impacts would not occur prior to the construction
effort and would no longer be evidenced upon completion and full operation of the proposed
North Atwater Bridge Crossing. However, in order to minimize neighborhood disruption and
local impacts to non-motorized traffic, the following measures are proposed:
■ Place appropriate signage to inform pedestrians, bicyclists and equestrians of access
around the construction area. Disabled access shall be maintained during construction
where feasible.
■ Notify local property owners, residences, and businesses on the east side of the river
near the construction area of major construction activities (e.g., utility
relocation/disruption, re-routing of delivery trucks, heavy equipment operation).

■ Coordinate with Caltrans staff to provide
advance notification of lane closures during
construction periods, to be posted on
Changeable Message Sign (CMS) boards on NB
Interstate 5, where feasible.
■ Develop reasonable detour plans for non-
motorized traffic as part of the proposed
strategies in the TMP. Include a public awareness
campaign to notify regular river users of the
forthcoming bikeway and pedestrian path
closures, provide temporary alternate routes
around the construction area, and provide
appropriate traffic systems and signage, traffic
support and safety elements. Potential alternate
routes include:
o L.A. River Greenway Trail Detour: Close pedestrian gate and equestrian trail at
Los Feliz Boulevard near Glenfeliz Boulevard. Close pedestrian gates on the
south side of Colorado Street, and all non-motorized access points to the east
side of the L.A. River near North Atwater Park. Provide detour route using
existing pedestrian facilities on Brunswick Avenue between Colorado Boulevard
and Los Feliz Boulevard.
o L.A. River Bike Path Detour: At Los Feliz Boulevard, close access to the bikeway
entrance on the north side of the street, and close overcrossing access on the
south side of the street. North of SR-134, close the bicycle path at Riverside
Drive. Provide detour route between Riverside Drive and Los Feliz Boulevard
using the existing Griffith Park Loop Bike Trail via Zoo Drive and Crystal Springs
Drive, west of the I-5.

Typical Detour Signs for Bike Path Closure along L.A. River during Construction Period
■ With the implementation of the TMP, potential temporary direct or indirect traffic and
transportation impacts to the non-motorized public are considered less than significant.
The proposed project (no alternatives) would have a beneficial permanent direct impact
on pedestrian, bicycle and equestrian traffic within the project area; however, existing
non-motorized traffic using the L.A. River between Colorado Boulevard and Los Feliz
Boulevard may experience longer travel times due to re-routing of these paths through
local streets and around the construction zone. With the addition of the above project
features, however, these impacts would be considered less than significant.
4.4 - Permits
It is anticipated that a Caltrans encroachment permit shall be required due to the necessary
temporary use of Caltrans’ operational highway right-of-way for the purposes of delivering and
loading/unloading of truck loads and construction materials during various times over the
construction period. The encroachment permit, along with accompanying project plans, will be
submitted in concurrence with the City of Los Angeles, and approved by Caltrans D7, Division
of Engineering Services (DES). A sample encroachment permit is provided in Appendix B. The

__________________________________________________________________________________ 21
08/06/2012
construction effort will also likely use a portion of this area for temporary staging purposes,
although the primary location for construction staging and parking activities will be performed
outside of Caltrans right-of-way and within the boundaries of the River (e.g., portions of the
existing bike path).
Due to the size and non-divisible nature of the bridge components which will be prefabricated
off-site and transported to the project site, one or more Caltrans transportation permits will
also be completed and submitted for approval. Tractor trailer combinations and/or body types
have not been specified at this time; however, the applicant will comply with Caltrans
Headquarters’ (HQ) special processing requirements for approval of special hauling equipment
which exceed the Department's standard weight classification methods. In addition, a variance
permit may be required for truck loads exceeding maximum 15' width, 17' height, and 135'
length dimensions. The completed transportation permit will also include relevant
documentation of the following travel details for each of the specified trips:
• Written route surveys for any load heights equal to or greater than 17'-0";
• Origin/destination and proposed route(s);
• Proposed fuel stops and turn outs;
• Obstacles, their owners (e.g., overhead CATV wires, telephone/utility wires, etc.)
and proposed avoidance measures;
• Critical turns, approximate speeds, and hauling times;
• Traffic control plans;
• Pilot car requirements; and
• Any additional required city/county permits. If a pilot car is required, then travel
would be permitted before sunrise and after sunset Monday through Friday, with
additional travel restrictions for the L.A. area (i.e., “no movement” curfew
between 6-9AM and 3-6PM). However, night and weekend travel could also be
requested for approval from Caltrans.
